All packages should be closely examined at time of delivery. If damage is
apparent, have notation of ”bad order” placed by the delivering driver on
all copies of the freight or express bill. If damage is of a concealed nature,
notify transportation agent as soon as possible to make an ”inspection report
of damage” but in any event not later than 15 days after delivery. A transportation company usually will not pay a claim for concealed damage if an
inspection is not requested within this 15 day period. Complete instructions
regarding claim procedure are found in section ”S” of the Policy & Procedure Bulletins.
If shipment was handled by moving van service - uncrated - call Traffic Milwaukee immediately when any damage is found. Do not attempt to call
any local agent. At this time be ready to describe type of damage, type of
equipment, serial numbers and if possible the order number.
The above paragraph is in regard to equipment requiring installation only,
and does not apply to supply items. The F.O.B. point for these items is as
shown in the Price Book.

System features
The key design goals of this system are:
• High Image Quality
• Increased User Productivity
• Multiple Clinical Applications
• Planned Upgradeability
• Higher Mobility
Types of Applications
The system supports many clinical uses. Scan and display parameters may be user selected to default to desired
values for each application. The system presets many parameters to clinically determined, optimal values.
• Radiology
• Cardiology
• OB/GYN, and
• Vascular
New design
User surveys and the latest technology were employed to increase console ease of use. Digital circuitry enables
more reliable and precise operation.
Faster service
Not only does up time increase due to the digital design, built–in diagnostic testing and tracking enable faster
service response. GE Service can access this information remotely if the unit is in warranty or the customer signs
an optional InSite Package Agreement. To enable this access, the customer must provide a dedicated, analog
phone line. GE’s National Support Center (NSC) can upload and download information for or about the customer’s unit enabling rapid resolution of a problem.

Subsystems
The system has one card cage that can be described by four functional subsystems: the kernel, beam former, mid
processor and back end processor.
Data flow
The ultrasound data path begins by translating the operator’s requests into commands and scan sequences
which have (vector parameters) delivered at the right moment to the appropriate circuit boards. Strong radio
frequency (RF) beams are transmitted and weak beams are received between the beam former, probe and the
patient. VME147S is provided as master–controller for the entire system. The VME147S is a VME bus but serves
as VIC bus (variant of the VME bus) for the mother–board to control each of the subsystems. The BMRC board
controls the scan using a master clock located upstream of the BMRC board. The BMRC board controls the USC
bus to control data which are to be controlled real–time and also controls the data transmission from the mid
system to back system through the USC bus. VIDO generates video clock, etc. The MASC board generates a
graphic and the DSCC board generates area signals for B, M, CFM, etc.

1–6–2 Doppler and CFM Middle Processor Assy Overview
The Doppler and CFM Middle Processor (DOPC) Assy is used only for the color monitor system. The Doppler and
CFM Middle Processor (DOPC) Assy consists of two blocks, doppler processing block and CFM processing block.
The CFM processing block receives I/Q–CFM signals from the Analog Signal Processor (ASPR) Assy for calculating
mean velocity, variance, and power of blood flow. The mean velocity, variance, and power of blood flow are displayed
on the CRT monitor screen using the Color Flow Mapping (CFM). The doppler block performs Fast Fourrier Transformation (FFT) and Logarithmical (LOG) compression to display its spectrum.
1–6–3 Doppler and CFM Middle Processor Assy Block Diagram Explanation
The Doppler and CFM Processor Assy components perform the following functions :
1.
USC and VIC Bus Interface (USC & VIC BUS) : Interfaces controls input and output of data and parameters to and
from USC and VIC buses. The registers in this block store parameters received from the CPU via VIC bus, and
parameters received via the USC bus. These parameters are used for signal processing.
2.
Controller : Supplies necessary parameters, which are stored in the register of the USC and VIC Bus Interface, to
process I and Q signals for each block in this board. The controller also supplies the ”sequence” to process one
echo line.
3.
Analog to Digital Converter (ADC) : Converts the I–CFM and Q–CFM signals supplied from the Analog Signal
Processor (ASPR) Assy from analog to digital signals.
4.
Pre–filter (PRE Filter) : Receives echo signals from the Analog to Digital Converter (ADC), and processes each
echo signal in the direction of (along the axis of) depth using ”moving–average” and ”down sampling” for an improved signal–to–noise ratio.
5.
Corner–Turner : Buffers echo signals from the pre–filter. The corner–turner consists of a 2–bank (banks A and B)
buffer. While output from the pre–filter is being written into bank A, data in bank B is read by the Color Flow Correlator(CFCOR). On the contrary, while output from the pre–filter block is being written into bank B, data is read
from bank A.
6
Color Flow Correlator (CFCOR) : Reads echo signal from the Corner–turner. I/Q data at each depth of echo
signal is processed by MTI filtering, and then by complex auto–correlation and power calculation.
7.
Look–up Table ( LUT(ROMs) ) : Receives echo signals from the Color Flow Correlator and processes the echo
signals to find the mean velocity and variance of blood flow at each depth based on the results of the complex
auto–correlation and power calculation received from the Color Flow Correlator. Also, these data are accepted or
rejected depending on the threshold power value.
8.
Clutter Detector : Distinguishes clutter information from the outputs of CFCOR block and sends them to Clutter
Rejector block.
9.
Clutter Rejector : Receives outputs from the Look–up Table block and the Clutter Detector. The clutter noise is
removed from signals depending on the information from the Clutter Detector block.
10. Noise Canceller : Receives outputs from the Clutter Rejector block and stores data in a previous acoustic frame.
The correlation between the data in a new frame and the data in a previous frame is implemented. When its result
indicates a “low–correlation”, the data sent to the next block is rejected. The redundant data is rejected as well
depending on the given threshold of power value.

11. Black Hole Canceller : Processes echo signals received from the Look–up Table based on the mean velocity or
power at the same depth as the three adjacent echo signals. This block then process the echo signals to ensure
no ”Black Hole” image appears on the CRT monitor during B–mode Color Flow Mapping.
12. Frame Averaging/Persistence : Receives signals from the Black Hole Canceller block and stores data in a previous acoustic frame. Data at the same depth and the same acoustic line is averaged. Otherwise, this block
compares data between new and old frames at the same depth and acoustic line, and either the data in a new
frame or the data in an old frame is captured or persisted.
13. Smoother : The mean velocity, variance, and power values are smoothed in the direction of (along the axis of)
depth.
14. 16–bit Analog to Digital Converter (16 bits ADC) for D–mode : Converts Pulse Doppler and Continuous Wave
Doppler analog signals (I and Q signal) into 16–bit digital signals.
15. Digital Signal Processor 1 (DSP1) : Performs Wall filter processing, I/Q balance correction, impulse noise reduction, segmented Doppler control for Pulse Doppler and Continuous Wave Doppler. The DSP also performs gain
control for Doppler signal, and decimation filter processing for Continuous Wave Doppler.
16. 12–bit Digital to Analog Converter (12–bit DAC) for audio signal : Converts digital signals into analog signals for
audio output of Doppler signals (I/Q). This block also includes an anti–aliasing filter.
17. Dual Port RAM 1 (DPRAM1) : Transfers signals from Digital Processor 1 to Digital Signal Processor 2.
18. Hilbert Transformer : Generates a forward/reverse audio signal from Doppler signals (I, Q) using a wide–band
(90 degree) phase shifter.
19. Digital Signal Processor 2 (DSP2) : Process 128–point FFT of Doppler signals, and signals for LOG compression, real-time auto–trace, base line shift, and spectrum invert.
20. Dual Port RAM 3 (DPRAM3) : Transfers FFT spectrum data (7 bits) from the Digital Signal Processor 2 to USC
bus.

1–15–2 Keyboard Assy Overview
The keyboard consists of control keys, alphanumeric keys, TGC potentiometers, a rotary encoder, and a trackball, etc.
The keyboard has a CPU. When a key is pressed, an inherent key code for that key is transmitted to the main system
(ultrasound scanner). Potentiometers, encoder and trackball, allow the amount of physical movement to be transmitted to the main system. The LEDs can be turned on and off under the control of the main system. For communication, quasi–RS232C is used with a Baud rate of 19.2 kbps. The keyboard is connected to the main system by a single
flat cable consisting of 30 conductors including those for serial communication signal and the system reset signal. The
keyboard is also supplied with a power of +5 V from the main system.

The Mother board’s main function is to provide a link, via connectors, through which each Assy (circuit board) in the
nest can communicate. Main buses and clock signals terminate at this Assy. The Mother Assy also has connectors for
connecting the assemblies inside the nest to those outside the nest. In addition, the mother board has a bus isolation
circuit located on the VIC and USC buses. During reception of echo signals, these buses are deactivated for both the
front end and mid processor to prevent noise from entering into the analog circuit.
